Study Notes
Neurotransmitter Synthesis and Breakdown
- Acetylcholine (ACh) is synthesized from choline and acetyl coenzyme A (acetyl-CoA) in the presynaptic neuron.
- Acetylcholinesterase breaks down Acetylcholine (ACh) into choline and acetate in the synaptic cleft.
Dopamine Synthesis
- Dopamine is synthesized from the amino acid tyrosine.
Serotonin Synthesis and Release
- Serotonin is synthesized from the amino acid tryptophan.
- Action potentials in serotonergic neurons lead to the release of serotonin into the synaptic cleft.
Dopamine Reabsorption
- Dopamine transporters are responsible for reabsorbing dopamine or breaking it down in the synaptic cleft.
Test your knowledge of the biosynthesis, release, action, and removal of Acetylcholine (ACh) neurotransmitter in this quiz. Explore the steps involved in ACh production, release into the synaptic cleft, and its action on the motor end plate.
